every (callback, target) Boolean
public
Returns true
if the passed function returns true for every item in the enumeration. This corresponds with the every()
method in JavaScript 1.6.
The callback method you provide should have the following signature (all parameters are optional):
function(item, index, enumerable);
-
item
is the current item in the iteration. -
index
is the current index in the iteration. -
enumerable
is the enumerable object itself.
It should return the true
or false
.
Note that in addition to a callback, you can also pass an optional target object that will be set as this
on the context. This is a good way to give your iterator function access to the current object.
Example Usage:
if (people.every(isEngineer)) { Paychecks.addBigBonus(); }
Parameters:
